Class QueryWrapperFilter

Constrains search results to only match those which also match a provided
query.

This could be used, for example, with a TermRangeQuery on a suitably
formatted date field to implement date filtering. One could re-use a single
QueryFilter that matches, e.g., only documents modified within the last
week. The QueryFilter and TermRangeQuery would only need to be reconstructed
once per day.

context - a AtomicReaderContext instance opened on the index currently
searched on. Note, it is likely that the provided reader info does not
represent the whole underlying index i.e. if the index has more than
one segment the given reader only represents a single segment.
The provided context is always an atomic context, so you can call
AtomicReader.fields()
on the context's reader, for example.
